If Pete is being passed by a vehicle on his left, what is the safest action for him?

When experiencing a scenario where another vehicle is passing on the left, the safest action is for the driver to stay to the right edge of their lane while maintaining or reducing speed. This behavior helps create adequate space for the passing vehicle and reduces the risk of a collision.

By staying on the right edge, Pete helps ensure that there's a clear path for the vehicle passing him, which is essential for safe maneuvering. If he accelerates to keep ahead of the other vehicle, it could lead to a dangerous situation as the other driver might misjudge the speed and distance. Moving to the left lane can also be risky; if there are other vehicles or obstacles in that lane, it could lead to unsafe driving conditions. On the other hand, drastically slowing down can confuse the other driver and increase the chances of a rear-end collision.

Therefore, maintaining a steady position and speed keeps the driving environment safer for everyone.
